Jack craned his head to look at the Master, trying to figure out what it was he was up to. He couldn't see very well, and his eyes were still adjusting as well. Clearly, some sort of sabotage was happening. "What are you doing?" He asked, not really expecting any kind of answer from him. At least, not a sincere one that would get him what he's looking for.

He narrowed his eyes at the Master and lifted his head to call out as loudly as he could into the TARDIS, hoping to be heard. "DOCTOR! DOCTOR, HELP!"
